david 191c70fd18 fix: replace cyclone env~ with vanilla line~ envelope, fix stripnote outlet
Validate and Test / validate-patches (push) Failing after 12s
Details 
- env~ is a cyclone external not available on board's Pd 0.55
- Replace with line~ + *~ 0.0055 for velocity-scaled AR envelope
- Fix stripnote outlet 1 (gate trigger) connected to envelope instead of outlet 0 (pitch)
- Change dac~ to dac~ 1 for mono output matching -outchannels 1
- Envelope: attack ~50ms, release ~50ms, sustain scaled by velocity

david 8d3666cdaa fix: replace hsl with loadbang floats for headless Pd
Validate and Test / validate-patches (push) Failing after 13s
Details 
hsl GUI objects don't initialize in -nogui mode, causing
cutoff at 0 Hz and volume at 0 → no audio output.
Use loadbang + float for headless-safe initialization.

david 290862a74e feat: add skills, version pinning, CI/CD, and generated-file headers
Validate and Test / validate-patches (push) Failing after 2m7s
Details 
- Create skills: rego-pd-validator, usb-gadget-configfs, led-matrix-msgpack-rpc
- Update pd-audio-synthesis skill with Uno Q specifics
- Add Pd version check (min 0.54.0) to start-synth.sh
- Add DO NOT EDIT headers to generated pd patches
- Add Gitea Actions CI workflow for patch validation
- Add ConditionPathExists guards to legacy systemd services
- Add 'just ci' recipe for CI

david 3cc497f632 refactor: 3-module pd architecture + viz non-blocking fix 
- midi-in.pd: netreceive -> route -> unpack -> pitch/velocity outlets
- audio-out.pd: inlet~ -> dac~ abstraction
- synth.pd: consumer patch wiring midi-in -> voice -> audio-out
- led-matrix-viz.py: router socket non-blocking, registered with poller
- pd.rego: skip outlet/abstraction false positives in validation
